The rotary motion of the motor is changed by the converter to produce the sweeping motion of the wiper arm. The motor runs at low or high speed, depending on the wiper speed chosen by a switch setting in the flight deck. A parking switch in the motor/converter sets the wiper blade to the park position when the wiper is turned off. The windshield motors use 28-volts dc power. A connector on each unit supplies power and control.
C. Windshield Wiper Arm
(1) The wiper arm connects the output shaft of the motor/converter to the wiper blade.
D. Windshield Wiper Blade
(1) The wiper blade consists of a wiper edge connected to a metal
channel. This channel attaches to the wiper arm.Operation
